The inventlon further. lflfiiglts to; provide the i n e tant mm h a mo phe e an to keep the fuelintactand gready for use by an outer seaLwh-ich is independent OftheQfuel Within hep niso that he b ke iwithout disturbing the fuel.

The invention further designs to provide a new and improved form of sup ort for the device which may becarriedi wit in the? device when it is not inuse, andwhich, when in use, dispenses with e the usual water pan employed-in connection with devices of this kind, to prevent thedevice from burning the table, floor or'sur-facegupon which thedeviee is set.

The invention furtherdesigns-to provide a new and improved form of fmnigator.

The invention further designs to provide an improved construction of the device set forth in Letters Patentof'the United States No. 1,009,816, dated November 28; 1911;

The invention consists in the severahfeatures hereinafter setgforth and more particularly defined by claims at the conclusion hereof.

3 i In the drawings: Figure 1 isa perspective view of! a fumigator embodyinggthe inven-" tion in operative position, Fig, 2 is a vert1- cal sectional view-thereof; Figefiis a detail perspective view, of the fue11 pan, wick and hield showing the interlqcking connecpan the shield. Fig. 4:

hasbeen sealed. Fig. is a vertical sectional view of the; device when sealed and packed for shipment. Fig; 6-is a section of the device sealed=and ready for-shipment;

I The fumigator cemprisesafuel receptacle, a disinfectant-receptacle, means for supportingthe disinfectant receptacleupon the fuel receptacle; anda snppo rt for the fuel receptacl'e.

The fuel receptacle comprises shallow panhhaving an annulargroove Sa in the bottom thereof andjinto which combustible fuel, fsueh: as paraflin, -isadapted to be placed: tubularw-ick 3; formed prefer- *ably of asbestosor nonheat conducting material and having plurality of i projecting arms 4 whichfradiate from the bottom of said wick and serve; as a support therefor, is

arranged centrally within the fuel pan 1. Am tubular shield and support 5 surrounds the wick 3* at its -reduced=bottom portion 5?,

being securedto the pan 1 and therebyisenectiongwhich consists ofa plate 6-: secured centrally tothe bottom of'thepam 1 bya rivetfii and having tongues thereon adapted to lit in corresponding notches "8 i in the bottom 5 of the tubular shield: 5g so-hthat,

when; the wick is arranged within 5 the pan 7 register with the 110130116385 the shield may be turnedto cause the tonguesto engage the said bottom of the shield 5 and secure the shield and wick to the bottom: of the pan. Fluid-v paraffin is then poured into thepan in an amountsufiicient to successfully carry on the vaporizing operation ofthe disinfectant within 3 the cup, and when the paraffin has congealed? it will secure this interlocking connection in locking position and theparaflin will beheld within the pan against removal by accidental dislodgment. The wick shield 5 has perforations 9 which alfordxventilationfor the fiaine from the wick-3-when the device is (in operation. The upper portion ofthe shie1d=5-is enlarged, as at 5, to fit cup 11 is flared at itsupper end; asshown at 127 "(Figsi 2 and 5) and has a: straight! pornon 14; at th e end adjacent the fflar e 12,

said upper p ortion being designednto fit within the pan 1 when the cup is inverted within the device when assembled for shipment.

In practice the parafiin is poured into the pan, as previously described, and, when in semi-solid condition, a suitable form is pressed down over it so as to remove the fuel from the side of the pan, so there will be -a channel with no paraflin therein adjacent the side of the pan, then the disinfectant cup with the disinfectant therein is inverted and placed into said channel. Sealingmeans are provided between the outside of the top portion 14 of the cup 11 and the side of the pan 1, which comprises a strip of cord or flexible element 15 and sealing fluid 16. The cord 15 is placed in the channel between the cup and the pan and pressed down firmly therein, after which sealing material 16, such as parafiin, is poured over the cord and into said channel and independently of the fuel in the pan to effectually seal the element within the pan and the cup from the atmosphere. To break the seal, all that is necessary is to grasp the free or projecting end 18 of the cord 16 and pull it out of the channel, which will result in cutting the seal 16 away from the sides of the pan and cup and permit of the removal of the cup. 1

' A cylindrical support 19 consists of a ring having therein a series of perforations 20, which is adapted to support the bottom of the pan 1 within the circular grooved portion 2 and by reason of the perforations permits air to circulate under the fuel pan and serves as an insulator to prevent the heat from the pan from scorching any table upon which the device may be set. As a further protection the ring 19 may be placed upon an asbestos mat 21 which is spread on the table or floor when the device is in use.

In devices of this kind it is necessary that they be put in as compact a package as possible. To provide for this the support and the mat have been constructed so that they may be placed within the tubular shield 5, they cup 11 placed in inverted position upon the pan and the whole device effectually sealed by the cord 15 and the seal 16.

The device set forth exemplifies one in which provision is made for effectually looking the wick shield to the fuel pan, so that any accidental dislodgment of the congealed paraffin or the fuel shield is prevented in the shipping or handling of said device.

The invention also exemplifies a fumigator in which provision is made for effectively connecting the wick shield to the fuel pan so that when the device is in operation and the paraflin hasbecome melted and liquefied,

neither'the wick shield and the cup supported thereon can he accidentally tipped from the :fuel pan.

' as a cover for the cup, so that When the combined cover and pan is separated from the cup the cup will not tend to break the paraflin fuel. The invention also exemplifies an improved insulating ring or support which may be placed under the fuel pan to prevent the floor or table on which the fu1nigator is used from being scorched and this insulator is constructed so that it may be packed and retained in the cup.

The invention is not to be restricted to the details set forth, since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention, what we claim as new and desire to secure by Letters Patent, is:

1. A fumigator comprising a fuel pan having a bottom, a disinfectant vessel, a separable and interlocking connection between the bottom of the pan and the support and a semi-solid fuel in which said connection is embedded.

2. A fumigator comprising a fuel pan, a disinfectant vessel, a support for the vessel, a wick extended between the pan and the support, a semi-solid fuel in the pan and in which the wick is embedded, and a separable interlocking connection between the pan and the support, and securing the wick independently of the fuel.

3. "A fumigator comprising a pan, a disinfectant vessel, a removable vessel support, a semi-solid fuel and wick in the pan,

an interlocking connection between the support and the pan comprising a plate on the pan and provided with tongues, the support having notches for the passage of said tongues and a flange to interlock with the tongues.

4. A fumigator comprising a fuel pan, a disinfectant vessel, a support for said vessel, and connected to the pan, a wick within the support, and a semi-solid fuel in the pan and in which the wick is embedded, said. support comprising a reduced tubular lower portion acting .as a shield around the wick, an enlarged upper portion and a portion between the upper and lower portions adapted for connection to the lower portion of the vessel, said support being adapted to pass into the vessel.

5. A fumigator comprising a disinfectant vessel, a fuel pan containing congealed fuel, adapted to form a cover for the vessel and having a flange. outside thereof, a sealing material independe t of the fuel between the flange and the rim of the vessel, and a strip embedded in said material between the flange and the vessel and adapted to break and remove the sealing material when it is 5 pulled apart from the pan. 6. A fumigator comprising a disinfecant vessel, a vessel support on the pan adapted to be placed into the vessel and a perforated ring smaller in diameter than the vessel 10 and cover, to adapt it to be placed in. the

vessel and separate from the fuel pan so that it may be placed under the pan when it is inverted and into the vessel when the pan is used as a cover.
